I call my pleco Godzilla because he's huge and when he swims around my tank he knocks down everything! I'm not sure what to do about this, because I get tired of constantly putting my plants and rocks back up (should I add more gravel?). He also is the biggest scardy cat ever (which makes me laugh at his name) and swims away as if you as much as touch the side of the tank. This causes more things to be knocked down and stirs up the gravel like crazy! I won't give him up though--he's the most fun to watch.
